怎么用脚本调用程序

在程序中调用脚本的方法有多种,以下是针对不同编程语言和环境的调用方法:

Java

方法1:使用 `System.Diagnostics.Process`

```java

import java.io.BufferedReader;

import java.io.InputStreamReader;

public class ScriptExecutor {

public static void main(String[] args) {

try {

Process proc = new ProcessBuilder("wscript", "hello.js").start();

BufferedReader reader = new BufferedReader(new InputStreamReader(proc.getInputStream()));

String line;

while ((line = reader.readLine()) != null) {

System.out.println(line);

}

proc.waitFor();

} catch (Exception e) {

e.printStackTrace();

}

}

}

```

方法2:使用 `ScriptControl`

```java

import com.ms.scriptcontrol.ScriptControl;

import com.ms.scriptcontrol.ScriptControlException;

import com.ms.scriptcontrol.ScriptEngine;

import com.ms.scriptcontrol.ScriptException;

public class ScriptExecutor {

public static void main(String[] args) {

try {

ScriptControl sc = new ScriptControl();

sc.setLanguage("JScript");

sc.setAllowUI(true);

String script = "function hello() { var WshShell = new ActiveXObject(\"WScript.Shell\"); var code = \"WScript hello.js\"; WshShell.Exec(code); }";

sc.addCode(script);

Object[] parameters = new Object;

sc.execute("hello", parameters);

} catch (ScriptControlException | ScriptException e) {

e.printStackTrace();

}

}

}

```

Python

方法1:使用 `subprocess` 模块

```python

import subprocess

def exec_shell(shell_path, params):

command = f"{shell_path} {' '.join(params)}"

process = subprocess.run(command, shell=True, check=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE)

return process.stdout.decode('utf-8')

示例调用

output = exec_shell("/usr/bin/python3", ["run.py", "arg1", "arg2"])

print(output)

```

方法2:使用 `os.system`

```python

import os

def exec_shell(shell_command):

os.system(shell_command)

示例调用

exec_shell("python3 run.py arg1 arg2")

```

C

方法1:使用 `system()` 函数

```c

include

int main() {

char cmd[] = "python3 run.py arg1 arg2";

system(cmd);

return 0;

}

```

方法2:使用 `popen()` 函数

```c

include

include

int main() {

char cmd[] = "python3 run.py arg1 arg2";

FILE *fp = popen(cmd, "r");

if (fp == NULL) {

perror("popen");

exit(1);

}

char line;

while (fgets(line, sizeof(line), fp) != NULL) {

printf("%s", line);

}

pclose(fp);

return 0;

}

```

总结

不同的编程语言提供了多种调用脚本的方法,选择哪种方法取决于具体的应用场景和需求。Java中可以使用`ProcessBuilder`或`Runtime.getRuntime().exec()`,Python中可以使用`subprocess`模块或`os.system`,C中可以使用`system()`或`popen()`。根据这些方法,可以根据具体的编程语言选择合适的方式来执行脚本。
